STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nadCNicotinate-nucleotide pyrophosphorylase; Belongs to the NadC/ModD family. (280 aa)    
Predicted Functional Partners:
nadB
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
 
 0.998
nadA
Quinolinate synthetase A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
 
 
 0.996
nadE
Glutamine dependent NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
 
 0.827
pncB
Nicotinate phosphoribosyltransferase; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Belongs to the NAPRTase family.
   
 0.808
yhaU
Na(+)/H(+) antiporter.
       0.792
murG
Undecaprenyldiphospho-muramoylpentapeptide beta-N-acetylglucosaminyltransferase; Cell wall formation. Catalyzes the transfer of a GlcNAc subunit on undecaprenyl-pyrophosphoryl-MurNAc-pentapeptide (lipid intermediate I) to form undecaprenyl-pyrophosphoryl-MurNAc- (pentapeptide)GlcNAc (lipid intermediate II); Belongs to the glycosyltransferase 28 family. MurG subfamily.
       0.792
Lcin_3107
Succinyl-diaminopimelate desuccinylase.
       0.792
nadD
Nicotinate-nucleotide adenylyltransferase NadD; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
    
 0.778
pyrB
Aspartate carbamoyltransferase; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
     
 0.683
rsfS
Ribosomal silencing factor RsfS; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
